Grime Box + Casio SK1 // LFO+ VCF+ DELAY

Six Oscillator Noise Machine // Filter + Resonance

http://marbeausynth.com/product/drone-delay/

This noise box has a triangle wave oscillator that’s modulated by an LFO & run through a dirty digital delay with a max delay time of about one second. A switch adds a square wave oscillator.

The lfo can be used to modulate the oscillator(s) pitch (adds a vibrato effect) or routed to the delay feedback. When modulating the delay feedback, the lfo moves feedback in & out at the set lfo speed.

A 1/4″ input connects directly into the delay portion of the circuit. The input works well with line level instruments such as synths, drum machines, toy keyboards, cd players, etc. Unbuffered guitar straight in would work, but will definitely be weak. Signal to noise ratio is far from hi-fi but this is a noise box after all.

THREE TRIANGLE WAVE OSCILLATORS
+
THREE STEP SEQUENCER
+
LIFT
at the heart of this box is the “lift” control that allows the oscillators to bypass the sequencer. with the control all the way down, the sequencer is in complete control & you’ll only hear one oscillator at a time. as you turn the knob, the oscillators begin to drone together & the sequencer becomes more & more subtle. with the knob turned all the way up, the sequencer has no effect & three oscillators shine simultaneously.
+
FILTER
12db/octave lowpass VCF with resonance
+
LFO
a triangle wave low frequency oscillator modulates the filter cutoff frequency AND the lift control. a switch changes the waveform modulating the lift to an aggressive square wave, or cuts off the path from LFO to lift completely
+
WAVEFOLDER
folds the wave in half & adds new harmonics. the control for this actually adjusts the gain going into the wavefolder, so it’s sort of a combined volume/wavefold control

Tridriver Drone Synth

This is a one-off project, impulsively made out of stuff laying around.

Nine simultaneous sawtooth oscillators scream through a 12db/octave low pass filter with wild squealing resonance. A dirty delay adds a layer of warmth & depth.

Touch Box

Dame is a Dual Amplitude Modulation Emitter. A curated analog noise source is split between two voltage controlled amplifiers. Then two skewable and psuedo-syncable LFOs modulate each other and the volume of the amplifiers. The results are meditative noise patterns, snare & hihat sounds, endless waves & sky, and harsh structural decay.
